RESUMO
OBJECTIVE: The primary aim was to investigate serial changes in the mechanical properties of the pectoralis major (PM), upper trapezius (UT), and sternoclavicular mastoid muscle (SCM) in breast cancer patients undergoing radiotherapy (RT) using a hand-held myotonometer. The secondary aims were to determine changes in subjective symptoms and to identify correlation with subjective results. DESIGN: A total of 42 breast cancer patients were enrolled in this longitudinal prospective study. Muscle properties of the PM, UT, and SCM were evaluated before RT, immediately after RT, and 4 months post-RT. Subjective symptom scales of pain and stiffness at rest/stretch of each muscle were evaluated. RESULTS: The PM showed significant side-to-side differences; the affected PM showed increased tone, stiffness, and decreased elasticity compared with the unaffected PM. The affected PM and UT showed significant time-dependent interactions. Stiffness of the affected PM at stretching was significantly higher 4 months post-RT than baseline. Only the tone and elasticity of the affected PM were correlated with subjective symptoms. CONCLUSION: In breast cancer patients who received RT after surgery, increased tone, stiffness, and decreased elasticity were observed in the affected PM compared with the unaffected side, which sustained four months post-RT. Change in muscle properties immediately after RT preceded subjective stiffness, which worsened significantly 4 months post-RT compared with baseline.

BACKGROUND: The prevalence of depression and type 2 diabetes mellitus (T2DM) are increasing in the elderly and are reportedly related to each other. We evaluated the relationship between T2DM-related factors and the degree of depression in elderly patients with T2DM based on gender. MATERIALS AND METHODS: A total of 155 patients with T2DM (56 males and 99 females aged ≥ 65 years) from seven hospitals were included in the study. To assess the status of depressive symptoms, the short form of the Geriatric Depression Scale-Korean version (SGDS-K) was used. We evaluated DM-related factors, such as T2DM duration, hemoglobin A1c (HbA1c) levels, and T2DM complications, as well as other possible factors that could affect depression, such as cognitive function, physical function, education level, and other personal factors. RESULTS: Mean age of the participants was 71.3 years with a mean HbA1c level of 7.6%. Males in the good glycemic control group (HbA1c <7%) showed lower SGDS-K scores compared to those in the poor glycemic control group, and the mean SGDS-K score was higher in the group with a longer duration of DM (M10 years); however, no difference was observed in females. Males and females with microvascular and macrovascular complications tended to have higher SGDS-K scores than participants with no microvascular or macrovascular complications. A multiple linear regression analysis revealed that DM duration and HbA1c level were independently associated with SGDS-K scores in males. CONCLUSION: Greater depression was associated with poorer glycemic control and a longer duration of DM in elderly males with T2DM.
RESUMO
BACKGROUND: With the increased incidence of diabetes mellitus, the importance of early intervention in prediabetes has been emphasized. We previously reported that fermented kimchi, a traditional Korean food, reduced body weight and improved metabolic factors in overweight participants. We hypothesized that kimchi and its fermented form would have beneficial effects on glucose metabolism in patients with prediabetes. METHODS: A total of 21 participants with prediabetes were enrolled. During the first 8 weeks, they consumed either fresh (1-day-old) or fermented (10-day-old) kimchi. After a 4-week washout period, they switched to the other type of kimchi for the next 8 weeks. RESULTS: Consumption of both types of kimchi significantly decreased body weight, body mass index, and waist circumference. Fermented kimchi decreased insulin resistance, and increased insulin sensitivity, QUICKI and disposition index values (p = 0.004 and 0.028, respectively). Systolic and diastolic blood pressure (BP) decreased significantly in the fermented kimchi group. The percentages of participants who showed improved glucose tolerance were 9.5 and 33.3% in the fresh and fermented kimchi groups, respectively. CONCLUSIONS: Consumption of kimchi had beneficial effects on glucose metabolism-related and anthropometric factors in participants with prediabetes. Fermented kimchi had additional effects on BP and insulin resistance/sensitivity. The percentage of participants who showed improvement in glucose tolerance was high in the fermented kimchi group.

A 21-year-old man with diabetic ketoacidosis (DKA) displayed short and clubbed fingers and marked eyebrow, which are typical of Hajdu-Cheney Syndrome (HCS). Laboratory findings confirmed type 1 diabetes mellitus (DM). After conservative care with hydration and insulin supply, metabolic impairment was improved. Examinations of bone and metabolism revealed osteoporosis and craniofacial abnormalities. The mutation (c.6443T>G) of the NOTCH2 gene was found. The patient was diagnosed with HCS and DM. There may be a relationship between HCS and DM, with development of pancreatic symptoms related to the NOTCH2 gene mutation.

Short sleep duration has been reported to increase the risk of diabetes. However, the influence of sleep duration on glycemic control in diabetic patients has not been clarified. In this study we evaluated the association between sleep duration and glycemic control in diabetic patients. We analyzed the data from the Korea National Health and Nutrition Examination Survey (KNHANES) 2007-2010. Sleep duration was classified into five groups: <6, 6, 7, 8, and ≥9 h/day. Fasting blood glucose and HbA1c showed a U-shaped trend according to sleep duration. Sleep duration of 7 h/day had the lowest HbA1c (7.26%) among the subjects (P=0.026). In the older age group (≥65 yr), a sleep duration of 6 h/day was associated with the lowest HbA1c (7.26%). The adjusted odds ratio (OR) with a 95% confidence interval (CI) of worse glycemic control (HbA1c ≥7.0%) in group of sleep duration of ≥9 h/day was 1.48 (1.04-2.13) compared with the group of 7 h/day. This relationship disappeared after adjusting duration of diabetes (OR, 1.38; 95% CI, 0.93-2.03). Our results suggest that sleep duration and glycemic control in diabetic patients has U-shaped relationship which was mainly affected by duration of diabetes.

BACKGROUND/AIMS: Liver biopsy is a standard method for diagnosis of liver cirrhosis in patients with chronic hepatitis. Because liver biopsy is an invasive method, non-invasive methods have been used for diagnosis of compensated liver cirrhosis in patients with chronic hepatitis. The current study was designed to evaluate the usefulness of ultrasonography and routine blood tests for diagnosis of compensated liver cirrhosis in patients with chronic viral hepatitis. METHODS: Two hundred three patients with chronic viral hepatitis who underwent liver biopsy were included in this study and ultrasonography and routine blood tests were analyzed retrospectively. Ultrasonographic findings, including surface nodularity, parenchyma echogenecity, and spleen size, were evaluated. The diagnostic accuracy of ultrasonography and routine blood tests were examined. RESULTS: Discriminant analysis with forward stepwise selection of variables showed that liver surface nodularity, platelet count, and albumin level were independently associated with compensated liver cirrhosis (p<0.05). Cross-tabulation revealed that the following 4 variables had >95% specificity: platelet count <100,000 /uL; albumin level <3.5 g/dL; INR >1.3; and surface nodularity. If at least one of the four variables exists in a patient with chronic viral hepatitis, we can predict liver cirrhosis with 90% specificity and 61% sensitivity. CONCLUSIONS: These results suggest that four variables (platelet count <100,000 /uL, albumin level <3.5 g/dL, INR >1.3, and surface nodularity) can be used for identification of liver cirrhosis in patients with chronic viral hepatitis with high specificity.

BACKGROUND: Exercise is predicted to have a positive effect among hepatocellular carcinoma (HCC) patients. However, these patients are hesitant to start and build up an exercise program for one major reason: the vague fear of developing hepatic decompensation, a potentially fatal condition that can lead to death. Integrating mobile health (mHealth) with individualized exercise programs could be a possible option for promoting physical capacity among HCC patients. OBJECTIVE: The aim of this study was to evaluate the efficacy and safety of rehabilitation exercises, which have been individually prescribed via an mHealth app, on physical fitness, body composition, biochemical profile, and quality of life among HCC patients. METHODS: A total of 37 HCC patients were enrolled in a 12-week course with an mHealth app program targeted to HCC patients. The wearable wristband device Neofit (Partron Co) was provided to participants, and recorded daily physical data, such as the number of steps, calorie expenditure, exercise time, and heart rate. Each participant was given an individualized rehabilitation exercise program that was prescribed and adjusted at the 6-week midintervention period based on the assessment results. At baseline, 6-week, and 12-week sessions, participants' physical fitness levels (ie, 6-minute walk test, grip strength test, and 30-second chair stand test) were measured. Physical activity levels, as measured by the International Physical Activity Questionnaire-Short Form (IPAQ-SF); body composition (ie, body mass index, body fat percentage, and muscle mass); biochemical profiles; and quality of life, as measured by the European Organization for Research and Treatment of Cancer Quality-of-Life Questionnaire C30, were assessed at baseline and at the end point. At the 6-week midpoint, exercise intensity was individually adjusted. RESULTS: Of the 37 patients, 31 (84%) completed the 12-week intervention. Grip strength improved significantly after 12 weeks of the intervention. The 30-second chair stand test and the 6-minute walk test showed significant improvement from 0 to 6 weeks, from 0 to 12 weeks, and from 6 to 12 weeks. Muscle mass and the IPAQ-SF score increased significantly after 12 weeks of the intervention without biochemical deterioration. CONCLUSIONS: Following 12 weeks of mHealth care, including an individually prescribed rehabilitation exercise program, we saw significant improvements in physical fitness, body composition, and physical activity without any complication or biochemical deterioration among compensated HCC patients who had completed therapy.

BACKGROUND: The use of a mobile health care application, the delivery of health care or health care-related services through the use of portable devices, to manage functional loss, treatment-related toxicities, and impaired quality of life in cancer patients during chemotherapy through supervised self-management has been increasing. The aim of the present study was to evaluate the efficacy and feasibility of comprehensive mobile health care using a tailored rehabilitation program for colorectal cancer patients undergoing active chemotherapy. PATIENTS AND METHODS: A total of 102 colorectal cancer patients undergoing chemotherapy underwent 12 weeks of smartphone aftercare through provision of a mobile application and wearable device that included a rehabilitation exercise program and information on their disease and treatment. The grip strength test, 30-second chair stand test, 2-minute walk test, amount of physical activity (International Physical Activity Questionnaire short-form), quality of life (European Organization for Research and Treatment of Cancer Quality of Life Questionnaire C30), and nutritional status (Patient-generated Subjective Global Assessment) were assessed and measured at baseline, at mid-intervention (6 weeks), and at completion of the intervention (12 weeks). The rehabilitation exercise intensity was adjusted by the test results at every assessment and through real-time communication between the patients and clinicians. RESULTS: Of the 102 patients, 75 completed all 12 weeks of the smartphone aftercare rehabilitation program. The lower extremity strength (P < .001) and cardiorespiratory endurance (P < .001) was significantly improved. Fatigue (P < .007) and nausea/vomiting (P < .040) symptoms were significantly relieved after the program. CONCLUSION: A tailored rehabilitation exercise program provided through a comprehensive mobile health care application was effective in improving patients' physical capacity and treatment-related symptoms even during active chemotherapy.

BACKGROUND: Hypopituitarism is associated with osteoporosis and osteopenia especially when hypogonadotropic hypogonadism is present. Despite hypopituitarism being an important cause of secondary osteoporosis, osteoporosis in patients receiving surgery for pituitary tumors in Korea has not been studied. In this study, we evaluated the effects of testosterone replacement therapy (TRT) on bone mineral density (BMD) in postoperative hypogonadal patients with pituitary tumors. METHODS: To examine the effect of TRT on BMD, we performed a retrospective observational study in 21 postoperative male patients who underwent pituitary tumor surgery between 2003 and 2012 at the Ajou University Hospital. Testosterone was replaced in postoperative hypogonadal patients by regular intramuscular injection, daily oral medication, or application of transdermal gel. BMD (g/cm(2)) measurements of central skeletal sites (lumbar spine, femoral neck, and total femur) were obtained using dual-energy X-ray absorptiometry (GE Lunar). For lumbar spine BMD, L1 to L4 values were chosen for analysis. Femur neck and total femur were also analyzed. RESULTS: During the follow-up period (mean, 56 months; range, 12 to 99 months) serum testosterone levels increased with the administration of TRT (P=0.007). There was significant improvement (4.56%±9.81%) in the lumbar spine BMD compared to baseline BMD. There were no significant changes in the femur neck BMD or total femur BMD. We did not find any statistically significant relationships between changes in testosterone levels and BMD using Spearman correlation analysis. CONCLUSION: Our results indicated that TRT used in the postoperative period for hypogonadal pituitary tumor surgery patients may have beneficial effects on the BMD of the spine.
RESUMO
BACKGROUND: The prevalence and social burden of type 2 diabetes mellitus (T2DM) is increasing. Medication adherence is necessary for positive outcomes in patients with T2DM. OBJECTIVE: This study evaluated the association between medication adherence and clinical/economic outcomes in patients with T2DM in the Republic of Korea over a 3-year period. METHODS: This study used data from the Korean National Diabetes Program at 5 hospitals. Medication possession ratios of ≥90% and <90% were used to define adherent and nonadherent groups, respectively. The degree of glycemic control, changes in blood pressure and lipid profiles, and health care costs were compared. RESULTS: Of the 608 patients, 472 were medication adherent and 136 were nonadherent. The adherent patients displayed improved fasting blood glucose and hemoglobin A1c during the study. Diastolic blood pressure and total cholesterol were lower at 36 months, and lower low-density lipoprotein cholesterol was noted at baseline and 24 months. The total health care costs were $1861, $2060, and $1924, respectively, versus $1617, $1751, and $1602 during the 3-year study period for the adherent group versus the nonadherent group, respectively (P = 0.316, 0.627, and 0.172, respectively), whereas the outpatient drug costs were $1143, $1176, and $1162 in the adherent group versus $925, $778, and $914 in the nonadherent group (P = 0.002, P < 0.001, and P = 0.001). CONCLUSIONS: The adherent patients displayed better glycemic control and lipid profiles. Medication-related expenses were higher in the adherent group, but overall health care costs, including hospitalization costs, were similar between the 2 groups.

We investigated the effects of fibroblast growth factor-21 (FGF-21) on palmitate-induced insulin resistance in skeletal muscle myotubes. First, to determine the effect of FGF-21 on palmitate-induced insulin resistance, we measured 2-[N-(7-nitrobenz-2-oxa-1,3-diazol-4-yl)amino]-2-deoxy-d-glucose uptake and levels of proteins involved in insulin signaling pathways (IRS-1 and Akt) in human skeletal muscle myotubes (HSMMs) exposed to palmitate for 24h, and compared HSMMs exposed to palmitate and different doses of recombinant FGF-21. Second, to determine the mechanisms underlying the contribution of FGF-21 to palmitate-induced insulin resistance, we compared levels of proteins linked to palmitate-induced insulin resistance (PKC-θ, IKKα/ß, JNK, p38, IκBα, and NF-κB) in HSMMs exposed to palmitate and different doses of recombinant FGF-21 for 24h. Palmitate-reduced glucose uptake was restored by FGF-21. Palmitate inhibited phosphorylation of Akt and thereby impaired insulin signaling in HSMMs. FGF-21 prevented palmitate from inhibiting the phosphorylation of Akt. These results indicate that FGF-21 prevented palmitate-induced insulin resistance in HSMMs. Palmitate activated NF-κB in HSMMs, thereby impairing the action of insulin and initiating chronic inflammation. FGF-21 inhibited palmitate-induced NF-κB activation in HSMMs. The results of the present study suggest that FGF-21 prevents palmitate-induced insulin resistance in HSMMs by inhibiting the activation of stress kinase and NF-κB.

AIMS: Fibroblast growth factor 21 (FGF21) is an important regulator of glucose/lipid metabolism. Although there are studies examining the relationship between serum FGF21 levels and glucose homeostasis, the role of FGF21 remains unclear. The objective of this study was to examine whether serum FGF21 levels are associated with metabolic parameters in subjects with varying degrees of obesity and glucose tolerance and with complications in subjects with type2 diabetes mellitus (T2DM). METHODS: The study consisted of 213 subjects who were lean and had normal glucose tolerance (lean NGT), were overweight with NGT, had impaired glucose tolerance (IGT) or had T2DM. Serum FGF21 levels and their associations with the parameters of adiposity, glucose tolerance and the presence of diabetic complications were examined. RESULTS: The serum FGF21 levels in T2DM were higher than in lean NGT. Serum FGF21 levels showed a positive correlation with the urine albumin-to-creatinine ratio (ACR) in all subjects except for the T2DM subjects, who showed a correlation after adjustment of age, gender and body mass index. Moreover, the subjects with carotid artery plaque showed higher serum FGF21 levels than those without complications. CONCLUSION: Serum FGF21 levels were associated with the urine ACR and diabetic complications including carotid artery plaque.

BACKGROUND: Diabetes is a major health problem in Korea. However, interest in the quality of life in patients with diabetes is low. We examined the effects of diabetes on health-related quality of life (HRQoL) and compared it with HRQoL in the general Korean population using the Fourth Korea National Health and Nutrition Examination Survey (KNHANES IV) (2007-2009). METHODS: Using KNHANES IV data, we compared EuroQol (EQ)-5D and EQ-visual analogue scale (VAS) scores after adjusting for sociodemographic and psychosocial factors as well as for comorbidities (hypertension, heart disease, stroke, arthritis, and chronic renal disease). Logistic regressions were used to explore determinants for the lowest quintile HRQoL scales in the diabetes group. RESULTS: The mean age of the 14,441 enrolled subjects (6,129 men and 8,312 women) was 52.5±14.5 years. The mean EQ-5D and EQ-VAS scores were significantly lower in the diabetes group (EQ-5D. 0.87; EQ-VAS, 71.94) than in the non-diabetes group (EQ-5D, 0.94; EQ-VAS, 77.40) (P<0.001). Self-reported depressive symptom had a significant effect on lowering the EQ-VAS (odds ratio [OR], 1.7; 95% confidence interval [CI], 1.1 to 2.6) in the diabetes group. Stress level had a significant effect in lowering both the EQ-5D (OR, 2.0; 95% CI, 1.3 to 2.9) and the EQ-VAS (OR, 1.9; 95% CI, 1.3 to 2.9). HbA1c, diabetes duration, and treatment modalities had no significant effect on lowering HRQoL. CONCLUSION: Diabetes was clearly associated with impaired HRQoL compared with the non-diabetic population regardless of comorbidities. Therapeutic approaches should focus much more on the subjective perception of health in patients with diabetes.
RESUMO
Kimchi is a traditional fermented Korean food that has garnered international interest due to its various beneficial effects. Focusing on the effect of fermentation, this study hypothesized that consumption of fermented kimchi would have more beneficial effects compared with that of fresh kimchi on metabolic parameters that are related to cardiovascular disease and metabolic syndrome risks in overweight and obese subjects. Twenty-two overweight and obese patients with body mass indexes greater than 25 kg/m(2) were randomly assigned to two 4-week diet phases separated by a 2-week washout period (crossover design). During each diet phase, the subjects consumed either fresh or fermented kimchi. Anthropometric data showed significant decreases in body weight, body mass index, and body fat in both groups, and the fermented kimchi group showed a significant decrease in the waist-hip ratio and fasting blood glucose. Net differences in the systolic blood pressure, diastolic blood pressure, percent body fat, fasting glucose, and total cholesterol in the fermented kimchi group were significantly greater than those in the fresh kimchi group. There was also a tendency for a decrease in fasting insulin after consumption of fermented kimchi. Therefore, the ingestion of fermented kimchi had positive effects on various factors associated with metabolic syndrome, including systolic and diastolic blood pressures, percent body fat, fasting glucose, and total cholesterol, compared with the fresh kimchi. These results suggest that the maturity of kimchi (fresh vs fermented) may affect obesity, lipid metabolism, and inflammatory processes.

PURPOSE: With the increase in vancomycin use, adverse drug reactions (ADRs) associated with vancomycin have been reported increasingly more often. However, the characteristics of cutaneous ADRs with and without systemic reactions (SRs) have not been described. This study investigated the characteristics of spontaneously reported and assessed ADRs associated with vancomycin by a pharmacovigilance center. METHODS: ADRs (n=121) associated with vancomycin in 96 patients were collected from 2008 to 2009. Records from physician- and nurse-reported suspected cases of vancomycin ADRs, ADR type, latent period, and laboratory results were compared between cutaneous ADRs with and without SRs. RESULTS: The main vancomycin-related ADRs were skin rashes (47.9%), hematologic abnormalities (17.36%), fever (12.4%), and elevated serum creatinine (12.4%). Significant differences were observed in latent period (days) and the mean change in eosinophils (%) between cutaneous (9.21±9.71 and 1.4±3.4, respectively) and other ADRs (14.03±11.71 and -0.5±3.5, respectively). Twelve cases of cutaneous ADRs with SRs had been initially reported as cutaneous ADRs only. Mean changes in the eosinophil count were significantly higher for cutaneous ADRs with SRs compared to those without SRs. CONCLUSIONS: Skin rashes accompanied by peripheral eosinophilia, representing suspected immune-mediated delayed hypersensitivity reactions, are a common vancomycin ADR. For the early and exact detection of ADRs associated with vancomycin administration, close monitoring of laboratory tests, including complete blood counts with differential analysis, is recommended.
